    • 雖然電源轉換器在零電壓切換條件之下，可以降低輸出的切換雜訊，然而在負載越重及頻率越高的情況下，開關上跨壓變化的斜率也隨之變大，使得輸出雜訊隨之增加。因此本論文主要研究目的為針對切換式直流電能轉換器，進行開關切換雜訊干擾之研究。藉由對電感上跨壓的波形分析，探討開關切換時跨壓的變化對輸出雜訊造成的影響。本文並以主動雙橋同步整流降壓式轉換器(Dual-Active-Bridge Synchronous Rectification Buck Converter, DAB SR Buck)電路進行研究與設計減少輸出雜訊的方法，最終成功實現雙邊零切技術(Double Sides Zero Voltage Switching, DS ZVS)。在模擬軟體SIMPLIS與實作結果上得到驗證，1 kW條件下的DAB SR Buck相較一般硬切降壓式轉換器可減少76.9%開關切換雜訊。

    Although power converters can reduce the output switching noise under zero-voltage switching conditions, the voltage change slope cross- the switch also becomes larger while the load is heavier and the switching frequency is higher. More importantly, the switching noise increases with it. The main research purpose of this thesis is to study the switching noise interference of DC switching power converters. By analyzing the waveform of the voltage across the inductor, the effect upon the variation the voltage across the switch on the output noise is discussed. In this thesis, a Dual-Active-Bridge Synchronous Rectification Buck (DAB SR Buck) Converter is studied and designed to reduce the output noise, and a Double-Sided Zero-Voltage-Switching (DS-ZVS) control scheme is implemented to further reduce the switching noise. Simulation software SIMPLIS and experiments are applied to verify the proposed converter operated at 1 kW. The experimental results show that over 76.9% switching noise is reduced by the DS-ZVS scheme.
